A fox on a wall

I wish I could come up with a more imaginative title for this, but I can't. Several 'stupid like a fox' type phrases came to me, something about cunning, a parody of that Jimi Hendrix song. In the end I gave up. I just wanted to share with the world that this lunchtime, in Tesco's car park in Brixton, I saw a fox walking bold as brass along a ten foot wall. At lunchtime. In the middle of the day. Ten feet up!
